Abstract:The processing-production of nan was achieved by traditional hand-craft，but the traditional technology of nan making process will cause food contamination，the speed of processing was slow，low work efficiency and need more manpower，which can not meet the problems of large market demand of nan，therefore creating a pipelined nan machine which using electric start-up system seems very important.Pipelined automatic nan machine was designed based on traditional Nan making process，the whole stracture of nan mould and automatic nan machine were detailed designed，and the manner of working of the machine was determined.This research will change the traditional hand-made ways of Nan making technology，achieved mechanized and continuous manufacturing of it.The use of nan mould will reduce manpower，enhance the making speed and efficiency of Nan making.The experimental results of continuous manufacturing of girda nan making shows that：when the air pressure of air pump was 0.8 MPa，extrusion time was 1.5 s，the revolving speed of conveyer belt was 1.15 r/min，the environment temperature was controlled in 25℃-35℃and the fermentation time was controlled in 30 min，23.7 beautiful modelling，same-sized and completely shaped nan flan.Automatic nan flan machine will bring some convenience commercialization，standardization and industrialization of nan.
